Ghost Blog Sys-V init Linux Startup Script

Installing nodejs init script for Ghost Blog.

If you followed my guide on: Hosting your own blog with Ghost & Nginx on Linux

The following Linux init script should work as is, on
RHEL, Oracle Linux, SL, CentOS Linux distributions.

For other Linux distributions, minor adjustments should be expected.

Installing Ghost Blog init script

$ sudo vi /etc/init.d/ghostblog

^Add the below script to the file and save.

 $ sudo chmod 0750 /etc/init.d/ghostblog

^Make it executable and set permissions.

$ sudo chkconfig --add /etc/init.d/ghostblog

^Add the init scipt to services

$ sudo chkconfig ghostblog on

^Set the startup flag to on.

Testing:

$ sudo service ghostblog start
Starting ghostblog: 
$ sudo service ghostblog status
node (pid 24909) is running...
$ sudo service ghostblog stop
Stopping ghostblog: 
$ sudo service ghostblog start
Starting ghostblog: 
$ sudo service ghostblog status
node (pid 24963) is running...
$

ghostblog is configured to start and stop as a service.

Hope you enjoyed it!
